EXHAUST CUT-OUT.

Original application flle d May 13, 1921, Serial No. 469,217. Divided and. this application filed. September To all whom it may concern:

Be it known that I, EMIL R. DRAVER, a

citizen of the United States, residing at Richmond, in the county of Wayne and State of Indiana, have invented certain new and useful Improvements in Exhaust Cut- Outs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to exhaust cut outs for automobiles or other vehicles propelled by explosive engines. The present application is filed as a division of in pending application S. N. 469,217, filed ii Iay 13th, 1921, and entitled Exhaust cut-outs. The present application is particularly directed to a novel form of yoke or coupling for bridging the gap in the exhaust pipe, and the combination therewith of a supplemental pipe section moveable laterally, by sliding movements, into and out of alignment with a sleeve or the sleeves of said yoke, all as will hereinafter more fully appear.

Generally stated the invention consists of the novel construction and combination of parts hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a side elevation illustrating the manner in which the device may be applied to the exhaust pipe of an explosive engine, some parts of said device being broken away and some parts being sectioned;

Fig. 2 is a plan view of the parts shown in Fig. 1; and

Fig. 3 is a transverse section on the line 33 of Fig. l.

The numeral 8 indicates an exhaust pipe of an internal combustion engine, which pipe leads to the mutiier 9. In this arrangement, the exhaust pipe 8 is cut in twoand its severed ends are spaced so as to form a gap that is spanned by a coupling yoke that is preferably of rectangular form. For cooperation with the yoke just noted, I provide a supplemental pipe section 30 which is mounted for straight line vertical movement and has a depending deflector 31 located immediately adjacent thereto. This section 30 and deflector 31 are mounted for Serial No. 499,192.

straight line vertical movements through a rectangular yoke 32 which is open at top and bottom and on its front and rear ends is formed with sleeves 33 into which the sec tions of the exhaust pipe 8 are telescoped. The inner ends of the sleeves 33 are continuous or unbroken and'their faces are perpendicular to the axis of the sleeves 33 and the exhaust pipe, although, of course, the exhaust pipe, outside of the sleeves, may be bent or given any desired form;

*As here illustrated the outer portions "of the sleeves 32 are split and provided with supplemental sleeve sections 33 clamped to the main sleeves 33 and onto the ends of the 'the said pipe section to a position in which it is in alignment with the sleeves 33; and the stop 36 on the deflector 31 limits the movement thereof to a position in which said supplemental pipe section is above the sleeves 33 and the deflector is aligned therewith. o

It is important to note (see particularly Fig. 2), that there is considerable clearance between the supplemental pipe section 30 and the adjacent walls of the yoke and that the supplemental pipe section is guided and held against lateral displacement by narrow vertical guide ribs 30 formed on or applied to said pipe section and its depending deflector. This affords a good guide and the clearance noted permits good circulation of air to prevent overheating of the supplemental pipe section and yoke. Overheating would cause expansion of the iron and would cause the pipe section to stick in the yoke. The narrow guide ribs 30 can be machined to fit reasonably close against the walls of the yoke and thus prevent rattling, without danger of sticking under the action of expansion.

The exhaust-controlling device, made up of the supplemental pipe section and its de flector, has only two lines of exhaust, to wit: to the mufller and to the atmosphere, and it may be set in an intermediate position so as to cause exhaust partly to the mufller and partly to the atmosphere, and such setting will produce a horn-like blast or sound that will serve the purpose of a horn or signal.

From the above it must be obvious that the invention described is capable of modification as to details of construction and arrangement without departing from the spirit of my invention, as herein disclosed and claimed.

l/Vhat I claim is:

1. A cut-out device comprising a yoke adapted to span a gap in an exhaust pipe, the yoke having axially spaced sleeves, the inner ends of which are in parallel planes to which the common axis of the sleeves is perpendicular, in combination with a supplemental pipe section mounted for sliding movements in a plane that transversely intersects the axis of said sleeves, into and out or" registration with said sleeves, and in which the sides of said supplemental pipe section are provided with narrow vertical guide ribs that engage the adjacent sides of said yoke, the body of said supplemental pipe section being spaced with considerable clearance from the side walls of said yoke,

so as to permit free circulation of air therebetween.

2. A cut-out device comprising a yoke adapted to span a gap in an exhaust pipe, the yoke having a sleeve with a complete or unbroken end that is in a plane to which the axis of the sleeve is perpendicular and exposed in said gap, in combination with a supplemental pipe section mounted for slid ing movements in said gap and in a plane to which the axis of the sleeve is perpendicular, into and out of registration with the sleeve of said yoke, and in which the sides of the supplemental pipe section are provided with narrow .guide cribs that engage the adjacent sides of the yoke, the body of said supplemental pipe section being spaced with considerable clearance from the side walls of said yoke, so as to permit free circulation of air therebetween.

A cut-out device comprising a yoke adapted to span a gap in an exhaust pipe, the yoke having axially spaced sleeves, in combination with a supplemental pipe section mounted for sliding movements within said yoke and provided with narrow :guide ribs that engage the adjacent sides of said yoke, the body of said supplemental pipe section being spaced with considerable clearance from the side walls of said yoke, so as to permit free circulation of air therebetween.

In testimony whereof I afiix my signature.

EMIL R. DRAVER.
